While we're on that subject, why is a safety heater needed in a highly
exothermic system? ("Safety heater" is Rossi's expression)
Why does the large band "safety" heater which surrounds the original E-cat
heat only (certainly mostly) the cooling water directly? How is the output
power of the cell regulated? What devices are used to control it and how
are they connected and where do they get their sensor input? What sensors
are used and where are they located. Why was Rossi tweaking the heat in
mid experiment during the session dissected by Krivit in which Rossi peers
nervously about and says "stable, stable"? How does a safety heater quench
the reaction? I bet if you ask Rossi, he will tell you (in my opinion
without reason) that all this is secret. I could give you my opinion of
why it's secret but I already said it many times.
Note that when Rossi wants the system to shut down, he accomplishes it by
increasing coolant flow from self sustain mode, and when the heater was on,
by shutting it off. Note that in so-called self-sustaining mode, he does
not shut off the device by turning on the safety heater. This whole
business of heaters for safety (or for that matter 1/6 input power to
output power for safety) doesn't make any sense unless you use extremely
convoluted and bizarre reasoning. Even then, it would be much better done
in a simpler way.
I'd still like to see one lovely gargantuan explosion -- out in the desert
where it couldn't hurt anyone. With good measurements, it would be
possible to estimate the yield and from the device's size and mass, one
could get a clue about whether or not it was nuclear. On another forum,
when I mentioned that, someone objected that Rossi doesn't want to
emphasize explosions. If so, he wouldn't mention them himself as he has
done on his blog in trying without success to explain why a power
generating device uses a large heater for safety.
